White cloud mountain minnows breeding

Heyyy, not sure where to post it and I can only assume this is the best place.

I currently have 5 white cloud mountain minnows in my tank and their tank mates are 3x synodontis petricolas and a flash pleco so they are the only mid-water fish. Two of the females have got BIG stomachs so I am expecting eggs. Will the petricolas eat the eggs, if yes I will be getting a fry saver cause I would like some minnows to add to their school.

Thanks.
